Hi to the group!

Has anyone tried to combine 'flying' through a model with
viewpoint tracking for the observer? It is 'next on the list'
for me to do and I was hoping for a couple of hints.

It looks to me like I will have to forgo the standard
pfiXformerAutoInput function and capture the
mouse/time changes to a DCS or a pfMatrix. Then
I will add the 'delta' from the tracking sub-system
to get a final viewpoint value, modify the frustums
(stereo) on the master channel, and we are done.

But, I could be wrong as - so far - I have only skimmed
the man pages.

Before I start down a wrong path, can anyone tell me
anything to help??

Thanks!
